Title: Formation of foamed slag on molten stainless steel in electric furnace
Inventor: GUILLOT YVES
IPC: C21C5/54
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To form stable formed slag on molten stainless steel by introducing powder containing metallic oxide and carbon into the slag to bring it into reaction and forming gas composed of the metallic oxide and bubbles composed of carbon monoxide in the slag. SOLUTION: At the time of producing the stainless steel in an electric furnace, the metallic oxide and the carbon in the powder forms are introduced into the furnace and the slag. The metallic oxide is reduced and the carbon and the gas of metal element in the oxide is produced, and the carbon monoxide is also produced. The bubbles produced from these gases are enclosed in the slag and the slag in the stable bubble shape is formed on the molten stainless steel. In this method, fir the metallic oxide, the oxide of voltile element selected from zinc and lead oxide, is used. For at least a part of powder, fine powder generated in the electric furnace for producing the steel is used. These powders are introduced by injection in the form of dry fluid.

Title: Liquid cooker
Inventor: MURAHATA SHUHO
IPC: A47J37/12
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce cost and improve operability by changing the pre-purge time according to the elapsed time from the right-before combustion stop and by selecting an appropriate pre-purge without providing a combustion interruption switch, etc. SOLUTION: This liquid cooker is so constituted that either pre-purge time is selected according to the right-before combustion stop time irrelevant to turning-on/off of an operation switch 19 so that in filtering, the pre-purge time is determined by a time necessary for the filtering, namely the combustion stop time. In general, the filtering itself completes in about 5 minutes so that this constitution can eliminate the delay in restarting the cooking caused by the 80-second long pre-purge performed for every filtering and quickly return to the continuous operation after only 5-second pre-purge. This constitution can also dispense with a special constitution as providing a combustion interruption switch and temporarily combusting it with the operation switch 19 turned on, so as to reduce the cost and to improve the operability.

Abstract: PURPOSE:To reduce the center distance of motor axes and to improve the transmission efficiency of turning force, by loosely fitting the main axis of a motor at one side to the recessed part of the stator frame of a motor at the other side, in a titled device for driving a rolling mill. CONSTITUTION:In a bottom-forward type titled device, for instance; a recessed part 11a penetrating in the axial direction is provided to the upper part of the main stator frame 11 of a lower motor 3. The intermediate main axis 9 of an upper motor 2 is penetrated through a space formed by the part 11a and a sub-stator-frame 12 attached detachably to the upper surface of frame 11. By this constitution, the center distance C1 of the main axes 6, 7 of both motors is made smaller than that of a conventional constitution.

Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To simply control the pouring quantity of molten metal at a low cost by providing a drawing plate in a molten metal pouring passage with a bottom pouring of the molten metal and reducing the cross sectional area of the pouring passage so that the opening area of the drawing plate as the time of pouring the molten metal elapses, is made larger with the effect of the poured molten metal. SOLUTION: A drawing plate 5 is provided in a molten metal pouring passage 3 at the upstream side from a sprue 6. The molten metal is poured into a mold from a sprue cup 8 in the pouring passage 3. Since the area of an opening port 7 in the drawing plate 5 is small, the molten metal is slowly filled in the pouring passage 3 at the downstream side of the throttle plate 5 and made to flow into a mold cavity 2. The opening port 7 is melted with the molten metal and gradually becomes large. The thickness of the drawing plate 5 is desirably set so that the opening port 7 equals to the area of the pouring passage 3 at the point of time when the die cavity 2 is filled by 1/3 and the disturbance is not caused on the surface layer of the molten metal.  The material of the drawing plate 5 is made of the same material as the molten metal so as not to deteriorate the purity in a casting even in the case that the drawing plate 5 is melted and mixed into the casting.
